Magnetic Effect Question 1.
The magnetic field of which magnets are depicted?
Answer:
Bar magnet
Soft iron core (Electromagnet)
Magnetic Effect of Electric Current Class 10 Notes Question 2.
How can you identify the direction of the magnetic fields?
Answer:
The presence of the magnetic field and the polarity can be understood using a magnetic compass. The direction of the magnetic fields can also determine using the Right hand thumb rule of James Clark Maxwell. Magnetic field lines are continuous, forming closed loops without beginning or end. They go from the north pole to the south pole.
Magnetic Effect of Electric Current Question 3.
How can you find out the polarity of these magnets using a magnetic compass?
Answer:
If the North end of the compass needle is j pointing toward your magnet, if it attract you have found the South pole of your j magnet. Rotate the other side of your magnet toward the compass; the South end of the compass needle will now be pointing directly to the North pole of your magnet.

Magnetic Effect of Electric Current Solutions Question 4.
What are the main differences between the magnets in the picture?
Answer:
The first figure indicates the magnetic field lines of the bar magnet, second figure indites the magnetic field lines of a electromagnet.The magnetic strength magnetism of an electromagnet is temporary while magnetic strength of a bar magnet is permanent.

Magnetic Effect of Electric Current Class 10 Solutions Question 6.
Find out the answer for the following based on the experiment.
→ What might be the reason for the deflection of the magnetic needle?
Answer:
A magnetic field is created which repels the magnetic needle. It is due to the current flow through the conductor. A magnetic field is created around a conductor when current flows through it.
→ Does the deflection depend on the direction of current?
Answer:
Yes

Is the direction of current in the circuit between A and B from A to B or from B to A?
Answer:
From A to B
→ Examine whether the direction of magnetic field lines around X are in the . clockwise or anticlockwise direction by observing the North Pole of the magnetic compass.
Answer:
Anticlockwise direction
